CaP-Bioglass composite coating by galvanic deposition

Orthopedic devices are increasingly used in our life to improve the health of patients after bone fractures due to accidents, aging, or sports injuries. Metallic materials (i.e. stainless steel, titanium alloys chromium alloys) are widely employed to fabricate prostheses, screws, and osteosynthesis plates. Although metals could be good mechanical properties like human bone, corrosion phenomena could occur, causing in the worst cases the failure of orthopedic implants. In addition, metal ions released around periprosthetic tissues could arise allergenic and cancerogenic effects. Nowadays, the research was focused on coating science to deal with these issues. In particular, the development of…

Galvanic deposition of Chitosan-AgNPs as antibacterial coating

Thanks to mechanical properties similar human bones, metallic materials represent the best choice for fabrication of orthopedic implants. Although metals could be widely used in the field of biomedical implants, corrosion phenomena could occur, causing metal ions releasing around periprosthetic tissues leading, in the worst cases, to the development of infections. In these cases, patients need prolonged antibiotic therapies that may cause bacterial resistance. Preventing bacterial colonization of biomedical surfaces is the key to limiting the spread of infections. Antibacterial coatings have become a very active field of research, strongly stimulated by the increasing urgency of identifying…
